MOTOR-VEHICLE.

To all whom it may concern:

Be 1t known that we, Famcis A. Mnssnnn and Mar ner. BOLLSTROM, citizens of the United States, residing at Battle Creek,

county of Calhoun, and State of Michigan, have invented certain new and useful Improvements in Motor-Vehicles, of which the following is a specification.

This invention" relates to improvements in motor vehicles.

The. main objects of this invention are,

"first, to provide in a motor vehicle, an improved drivin gear for the steering wheels;

second, to provide an improved driving :gear for the wheels of motor vehicles, which may be made comparatively light, and, at the same time, strong and durable.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

\Vc accomplish the objects of our invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure 'embodying the features of our invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which;

Figure 1 is a deta' plan view of a structure embodying the features of our inven-- tion. Fig. 2 is an enlarged detail, partially in vertical section. Fig. 3 is a detail section taken on a line corresponding to line 33 of Fig. 2, showing the driving gear connections for the wheels.

In the drawings, similar-reference characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the sect-ion lines.

In the accompanying drawing, we have illustrated only such parts of a vehicle as are necessary to fully illustrate our inven tion. The axle 1 is provided with pivoted spindles 2 for the wheels 3. The pivot for these spindles is preferably in the form of a knuckle 4 onthe axle, which is embraced by the yoke-like knuckle 5 of the spindle, the pivot 6' being arranged vertically These spindles are providedwith projecting arms 7, which are conirectedfby a link 8 to be operated together. The driving shaft 9 is connected through the compensating gear- 10 to the Specification of Letters Patent.

' sections 1111 of a driven shaft mounted in suitable bearings 12 carried by the axle.

As the details of the con'ipensating gear will be readily understood, they are not illustrated herein, they forming no part ofour invention, it being sufficient to say that the main gear 13 of the compensating gear meshes with a gear 14 on the driving shaft.

On the wheels 3 are external gears 15, and internal gears 16 arranged concentrically so that the gears 17 mesh with both. The gears 15 are loosely mounted and serve to support the gears 17. The gears 17 are mounted 'in suitable hearings provided in the upwardly-projecting arms 18' on the spindles. The gears 17 are connected to the shaft section 11 by means of a universal joint or coupling, the structure illustrated consisting of a pair of fork members 19 and 20, and a spherically connecting head 23 therefor, having circumferential grooves 2-1, therein, adapted to receive these forks. By this arrangement, 'the parts are effectively supported so that the strain thereon is re duced to a minimum, thus permitting the Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. The combination with an axle; wheels; spindles therefor pivoted on said axle, said spindles being provided with upwardly-proj ecting arms; a driving shift; a driven shaft made up of sections; compensating gear driving connections for said driving shaft and said driven shaft sections; bearings for said driven shaft sections arranged on said axle; gears; bearings'therefor arranged on said upwardly-projecting arms on i said spindles; universal joint driving connections for said driven shaft sections and said gears; and internal and external gears onsaid wheels arranged to mesh with said gears on said spindles.

2. The combination with an axle; wheels; spindles therefor pivoted on said axle; a driving shaft; a driven shaft made up of sections; compensating gear driving connections for said driving shaft and said driven shaft sections; bearings for said driven shaft sections arranged onsaid axle; gears caring connections for said driven shaft sections and said gears; and internal and external gears on said wheels arranged to mesh with said gears on said spindles.

3. The combination with an axle; wheels; pivoted spindles therefor, said spindles bemg provided with upwardly-projecting arms; gears; bearings therefor arranged on said upwardly-projecting arms on said spindles; shafts for said gears; bearings therefor carried by said axle; universal joint driving connections for said gears and said shafts; and internal and external gears on said wheels arranged to mesh with said gears on said spindles;

l. The combination with an axle; wheels; pivoted spindles therefor; gears; bearings therefor arranged on said spindles; shafts for said gears; bearings therefor carried by said axle; universal joint driving connec tions for said gears and said shafts; and internal and external gears on said wheels arranged to mesh with said gears on said spindles. v

5. The combination with an axle; wheels; pivoted spindles therefor; gears carried by said spindles; driving connections for said gears embodying universal. joints; and internal and" external gears on-said'wheels arranged to mesh with said gears on said spindles; n

6. The combination with an axle; wheels; pivoted spindles therefor; driving gears; and internal and external gears on said wheels arranged to mesh with said driving gears.

7. The combination with an axle of wheels; spindles therefor pivoted "on said axle; gears on said wheels; a driving shaft; a driven shaft made up of sections; compensating gear connectionsfor said drivingshaft and driven shaft sections; bearings for said driven shaft sections arranged on said axle; gears arranged to mesh with said gears on said wheels; bearings for said last named gears; upwardly-pro ecting arms on said spindles by which said bearings for said. gears are carried, said hearings on said axle and arms being substantially in alinement when the said spindles are in their central positionand universal joint driving connections ror said driven shaft sections tosaid mounted on said spindles, the pivotal erases center of said joint being in alinement with theaxes of the pivots for said spindles.

8. The combination with an axle of wheels; spindles therefor, pivoted on said axle; gears on said wheels; a shaft; bearings for said shaft arran ed on said axle ears arranged to mesh with said gears on said wheels; bearings for said last named gears; upwardly-projecting arms on said spindles, by which said bearings for said gears are carried, said bearings on said axle and arms being substantially in alinement when the said spindles are in their central position; and universal joint driving connections for said driven shaft sections to said gears mounted on said spindles, the pivotal centerv of said joint being in alinement with the axes of the said pivots for said spindles.

connection, said shaft being supported on said axle.

10. The combination with an axle having a knuckle member thereon; a wheel; a spindle therefor having a knuckle member and an upwardly-projecting bearing arm thereon; a pivot for said knuckle member; a gear on said wheel; a shaft and a connecting gear for said shaft to said gear on said wheel j ournaled in said bearing arm on said spindle, said gear being connected to said shaft by a universal joint, the pivotal center of said joint being in alinement with the axis of said knuckle pivot.

In witness whereof we have hereunto set our hands and seals in the presence of two witnesses.
